Customer Ratings & Reviews

Sound quality of the speaker is good. Not too bass heavy like the JBL one but the battery life seems to be really good based on early use. Connecting to speaker via UE app and iPhone was seamless. However I wish there were more equalizer preset options in the app. I have deduced one start for FEDEX delivery. They left the package out in the rain even when I buzzed them in.

Love it, this speakers sound good, bass all that i will delivered but few things i didnt like it, first no instructions to how to use it, second is loud but not to loud when u go to the beach i can heard loud n clear close to me, but after few meters far away so poor sound, that is my reason why return it, but is a good speaker tho sound amazing at home full it sound

I have used it nonstop since I bought it. Great quality sound, long lasting battery, and app is easy to use! Great for the beach!

Great device! Durable and very loud. I love it! Best portable speaker I’ve had yet.

Ue boom3 great sound take it to work...excellent product

I now have 4 high end BT speakers in the $200-$300 range, they all have strengths and weaknesses. The Mega Boom 3 is the lightest of the bunch at just about 3 lbs, nearly half the weight of any of the others, which weigh in between 6-11 lbs. Then battery life, the Megaboom 3 claims 20h, this is probably true if it's running at 25% volume, as you crank it up it will decrease battery life. 20h in a 3lbs package is truly impressive, my only other speaker that has 20h weights almost 9lbs. The megaboom3 comes with a pretty good size power brick (see picture) USB to micro USB connector. The back of the speaker has a rubber door to hide and protect the micro USB connector. With the USB door closed the speaker is IP67 waterproof (submersible) not just water resistant - wow; probably the best choice for your fishing boat, or paddle board. I'm not aware of any other speaker this size that is Waterproof. The speaker can also be charged with a (sold separately) charging pad (~$40 "PowerUp"). Given the size of the included power brick this might be a nice to have, but I didn't test with it. The speaker also has a nice woven loop towards the top so you can attach it to something. Volume; this speaker can get quite loud, easily my first or second loudest speaker, easily filling a 25'x18' room, maybe uncomfortably. But it really excels outdoors. The 360 degree sound, sounds better to me outdoors than inside. The Speaker includes an app to control it via Bluetooth, from a LONG range, I tested to over 100' no issues. The app also includes a 5 band graphic equalizer, which I found very helpful. The app can pair to with up to 150 UE Boom/Megaboom speakers, could be a lot of fun at a big beach party. Speaking of party the app also has a DJ function that allows you and 2 other friends to connect to the speaker(s) at the same time - pretty nice for a party. The app has a few pre-programed EQ curves, which I didn't find particularly useful/accurate -so they could improve these. SPeaking of improve the speaker's firmware can be updated from the app, so "things could change". The app can import play list from iTunes and Deezer, but no where else (for now). It can also show you your iTunes library/cover art - kind of nice, and it can control the volume from the app. This speaker does not have any fancy lights, only 2 led's on the top, to let you know it's on and to let you know it's in pairing mode (no problems pairing with my iPhone or my wifes andriod phone). The speaker does not have a RCA mini jack (my only speaker without this) so your going to use it with BT. Sound quality... not first or second of what I compared it to. The mids and vocals are not as brilliant or well pronounced as some similar BT speakers, The highs sound like other UE speakers, due to the 360 degree sound the highs are supposed to be reflected in all directions, but this, in my mind is only partially effective. The depth of the bass when cranked up, certainly over powers the mid-range. Used indoor this is particularity noticeable, moving it outdoors really improves the speakers sound. I'm not saying this speaker sounds bad, it's just not as crisp as I'd hoped to hear. When used at lower volumes, like in a dorm room the sound is pleasant but the highs won't impress you. I did some side by side listening with the first Boston album, it was punchy but not airy, I missed the preciseness of their strings throughout. Bringing the speaker outdoors, and moving away from it, it had a better balance. So like I said there are some compromises, this is not the best sounding speaker, but its not bad, and has many other features that may wow you. I missed the RCA connector but was impressed by the app, weight and battery life. It's far more portable than what I compared it to, so depending where and how you might want to use it, it may be a nice fit.

This is my second “Boom”. I have already used a BOOM2 for a while now and really like it. I have never used the “Party Up” feature before and was really excited to try it out. So this review will cover the MEGABOOM3, the Power Up charging dock and the Ultimate Ears app to control the two devices for Party Up. MEGABOOM3 –Do you know this is waterproof (IP67)? This paired to my phone effortlessly (Android Oreo). The sound quality is better than my BOOM2. The bass is significantly stronger. And although it is larger (see pictures) it is not too big in my opinion. Using the volume controls on the speaker work perfectly. Of course you can also use the app to control the volume. These speakers are durable and are perfect for use outdoors. I think they also sound better outdoors compared to indoors. The sound quality is on the bassy side as expected. Many will find this appealing. I found it was a little too much and this took away from the mids and highs. You can also play this very loud. The Bluetooth connection is strong and I kept a connection to the speaker up to about 100 feet away. Using the APP – In the Playstore (sorry do not know about the Apple experience), you will see a MEGABOOM app. DO NOT USE THIS ONE. It will not work. There is and Ultimate Ears BOOM and MEGABOOM app that works perfectly. You can control the volume, use different EQ settings (including a custom one you can configure) and PARTY UP. There is also a DJ feature that I did not use. PARTY UP – As I now had two UE speakers I was really excited to try this out. Once I had the correct app, I was off to try this new feature. I found when I paired my BOOM2 first and then added the MEGABOOM3; I was successful most of the time. If I paired the MEGABOOM3 first and then the BOOM2, I was often unsuccessful. A little frustrating at first. But once I figured it out, this was not an issue. Using the BOOM2 and MEGABOOM3 at the same time was a perfect balance. I could place the speakers apart from each other and fill a large size room very well. Even better when you are outside around the fire. They say you can connect 150 plus UE speakers. I know two works perfectly. I cannot imagine what 150 connected speakers would sound like. Power Up charging station – honestly, charging my Boom 2 was an inconvenience as I needed to plug it in and turn it upside down to charge it as the plug is on the bottom (the MEGABOOM3 plugs into the back near the bottom). The Power up comes with the charging base, AC adapter and charging D-Ring (for BLAST and MEGABLAST). This charging dock can be used for: BOOM3, MEGABOOM3, BLAST and MEGABLAST. You use the charging cable and AC adapter from your speaker. It works very well. I love the convenience of just placing it on the dock to charge! I wish it worked with my BOOM2. Final thoughts – the UE MEGABOOM3 is mega-bass. Overall the sound quality is good and loud. The sound quality is good and most will be happy. The features set it apart and make it a pick over many others - you can pair it with other UE speakers; it is waterproof; and you can connect it with up to 150 other UE speakers. My BOOM2 has been abused multiple times (dropped, left in the rain, etc.) and keeps on working. I recommend this to those looking for a Bluetooth speaker.

Product is good. When turned up all the way bass can get distorted. Good product other than that

This is the 3rd Logitech speaker I have used and ranks among the best of them. First, as always, sound quality is at the forefront of my mind and should be for anyone considering purchasing this model. As with all Megaboom models, it gets LOUD. Despite it's medium-ish size compared to other popular models, the sound can get plenty loud and cover a large area indoors or outdoors. The sound quality itself is very good, but I did slightly prefer other Logitech models like the Megablast. Other key features include the extensive battery life, listed at 20 hours. I've used mine for about 8 so far without needing to recharge. 20 hours will last you an entire weekend in most circumstances so it's nice not having to worry about having a place to plug in. Did I mention this thing is waterproof? I'm normally scared to take any electronics near water, but this speaker can not only float, but can also be submerged for up to 30 minutes. That's pretty cool and should make for excellent pool parties. This model has an optional charging station that you purchase if you would like to use it around the house and then just grab and go when you need to take it elsewhere. I imagine the charging time will be much better with the dock so consider that if you will be using the speaker frequently. My favorite feature of this model is the "magic" button. It's easy to locate on the top and can quickly be used to play/pause and skip songs with double presses. Also, if you want to fine tune your audio experience, the partner app allows you to use an equalizer to tweak to your favorite bass/mid/treble levels. At this price range it will be difficult for you to find a better all-around speaker with the features that this one has. My four star rating is only because I've had better audio quality at loud levels with other Logitech speakers in the past, but by no means is the audio quality poor.

This is the first portable Bluetooth speaker for us and I have to say I'm glad we finally have one. This MegaBoom 3 is pretty impressive with it's sound and loudness. I paired with my LG G7 ThinQ and listened to some music and the MegaBoom 3 filled our living room with a lot of sound! Highs and Mids are really good and Bass is good considering the size of MegaBoom 3. This thing gets pretty loud if you want it to. The unit it self is very easy to use with simple controls. I was surprised at how heavy the MegaBoom 3 is but it also makes it feel very well built and sturdy. I have used it for about 3-4 hours total so far on it's first charge. I really like the performance of the Ultimate Ears MEGABOOM 3 Portable Bluetooth Speake. If your in the market for a Portable Bluetooth Speaker this should be on your short list. I would have no problem recommending it to anyone.

Scale of 1 - 10 I score this speaker: 7 - 8 Sound - 8 Can’t go higher than half volume. A lot of bass even with bass reduced using the app. I thought 360 degree speakers/ sound would be great. Great sound but not really good for a big open area. Maybe if you had more than one of these speakers and connected them all together. Battery life - 6 The higher the volume the faster the battery dies. I had a JBL charge 3 and it’d go a full 10 hour shift at work almost full volume. JBL managed to balance the audio with superior battery life. Design - 8 It’s narrow can easily fit in a bag. Buttons are big. Volume up + Volume down - Pause and power are not labeled. Easy to figure it out tho. Connectivity - 9 Very easy to connect to your mobile device. Have to download the app to change the equalizer and view the battery percentage. Charging - 7 The charging port is on the back at the bottom and the light that lets you know it’s charging is a little light under the USB port. Should been one of the buttons on top that light up. I bought this on sale to take to work and gonna leave it at home because it just doesn’t produce the sound I need for my work. I bought this and got the 2 year warranty and spent $200ish all together. I use it at home and it’ll fill a room with good sound, but not good for big area. More browsing around should’ve been done before purchase. Recommend use is for maybe jamming at home or music when you’re cleaning your place or working in garage. Some where that is a smaller space.

I love UE Booms and my previous one lasted for almost 8 years before my battery stopped charging. I was really excited for this one being the upgraded version both in sound quality and battery life. While this one is good i figured i would be blown away by the difference and i just wasnt. It seems like they focused more on how water resistant it was and how you can throw it in a pool than user friendlyness. The new design has some features that bug me. You have to have the app in order to pair/use. There are two buttons on the top. The small one you use all the time is the power button, the big "magic button" one pairs when pushed and held to turn on...seems like they could have done this a different way. When you turn on the boom it makes the "on" schwoop/ pair noise at what sounds like full volume and cant be adjusted. All that said, for the money i dont think you can get a better unit. The only thing is this just left me wishing that my old speaker wasnt broken instead of being happy i upgraded to this one.

The Ultimate Ears Mega Boom 3 packs a serious punch in both sound and durability. Its impressive audio quality fills any space with rich, clear sound, while its rugged design makes it perfect for outdoor adventures. With its waterproof and dustproof construction, along with long battery life, this speaker is a true powerhouse. Whether you're at a party or on a camping trip, the Mega Boom 3 delivers an unbeatable audio experience. Highly recommended for music lovers on the go!

All around a great sounding speaker but definitely not ideal for those who love lots of bass. Very rugged so good for if you plan on taking it outdoors or near the pool or ocean as it also floats, although I would be wary of dropping it in salt water. The UE partyup feature is very nice if you have other UE speakers. I pair it up with my Hyperboom and it brings more clarity to the mids and highs. Overall worth the price if you have other UE speakers and want the connectivity but if you are looking at just this speaker then I would say there are better sounding options for the price.

It’s the perfect size. The volume is spot on. No distortion. The bass is amazing. It’s very rugged. Battery life is great. It last for days before it needs a charge. Love it.

I was looking for an alternative speaker system for our Can-Am X3 UTV. A few things that were really important to me: 1. I did not want to deal with the hassles of wiring in a stereo and speakers. -These speakers were perfect for this point. Party Up mode pairs all the speakers together, run the music right from the phone, and NO WIRING! 2. Looking for something less expensive than standard marine/UTV speakers -I bought 3 of these for $139 each (down to $125 now) for a total of $450. That's about half the cost of where audio systems for a UTV start. 3. Loud enough to be heard over a screaming UTV engine -These things get loud. Modern, high performance UTV engines are really loud and it can be hard to hear music over them. These delivered clear, crisp sound that could easily be heard over the engine without being painful on the ears. I will make an extra comment that I think this is largely due to the fact that we have 3 speakers instead of just one. Having the speakers positioned throughout the inside of the UTV helps to fill it with sound and enhances the music quality. We only had to turn the volume halfway to comfortably heard the speakers. 4. Portable (outdoor) speakers with flexible mounting options -We also use these speakers in our home gym and will also take them on other outdoor activities. These got covered in dust and still sounded great. Simply held them under a running sink and they look brand new. With a few velcro straps, it's also easy to find different places to mount them as the exterior material is very durable and showed no signs of wearing after 12 hours of high speed, off-road driving. Bonus item: the battery life is exceptional. Again, 12 hours of use over two days of off-road driving and the batteries in all three speakers are at ~40%. Con: if you have a lot of other bluetooth or wireless devices around, the phone app seems to pick those up as well and think they are UE speakers when you try to sync them for party mode. I have to find an area in my house free of other devices so that the app only picks up the 3 UE speakers. Also, other devices seem to cause a lot of interference and static noise. I have only experiences this in my home, never out on the trails but it is annoying when one speaker seems to have a weak bluetooth connection and is picking up static. Minus 1 star for these.

What an great overall speaker. I’m a big Sony Fan Boy and love the XB 33 and XB 43. But I got this for 99 dollars and it doesn’t have as much bass as Sony line or get as loud but it’s clear and It’s great to walk around with or ride your big out door. Yes I did get it a bit outdated with the old usb A port but. 99 bucks for a quality speaker with a representative brand too. 2 year warranty BOOM. I TRIED TONYATEBON IT BUT OVER ALL FOR 99 bucks it’s GREAT FOR ME. GOT IT IN BLUE AND IT LOOKS SO NICE. GET THE APP FOR FULL SPEAKER BENEFITS. ITS JUST A FUN SPEAKER TO HAVE.

Couldn’t resist the price for the value. Purchased my first UE Mega Boom 2+ yrs ago for full price and was most satisfied (sound quality & size/weight) until Bluetooth suddenly died. Decided then to “upgrade” with a pricey Sonos Move, whose sound quality and other features are great, but whose battery never holds a charge as advertised. Overpriced and bulky in size & weight. So, when $99 sale price for UE Mega Boom hit I couldn’t resist (re)purchase as a backup for travel purposes and convenience. Hoping Bluetooth lasts much longer this time...

Speaker gets really loud. Easy to take along with you. Nice Bass sound. Long lasting battery. Mega boom app really improves sound with equalizer

This is a great portable speaker. The sound is sufficient for the size, and my phone connects right away. My only quarrel with this is when I party up with my Hyperboom I notice some trouble with the connection. I'm sure it's a software fix, but if that worked flawlessly I would give the speaker a 5 star review.
